In this episode, set on Mardi Gras, a dying man coerces his relatives into wearing grotesque masks that reflect their true personalities.
It is also the Twilight Zone.On the night of Mardi Gras, wealthy Jason Foster is attended to by his physician, Dr. Samuel Thorne, who warns him that his death is imminent.
Following dinner, the family gathers in Foster's study, where he instructs them to put on special one-of-a-kind masks that he says were "crafted by an old Cajun."
He then informs them that the terms of his will require them to wear the masks until midnight in order to inherit his estate; if any of them unmasks before then, all four will receive only their return train fare to Boston.
The Harpers rejoice in their newly inherited wealth and unmask, but discover to their horror, that their faces now conform to the hideous features of their masks.
